Abstract: A fuel cell module has a fuel cell that supplies a drive power to a vehicle, a case that covers the fuel cell, and a current breaker that is attached to the case. The current breaker is manually operable from outside the case, and is capable of interrupting an output of the fuel cell to outside the case. The current breaker interrupts current at the time of a manual operation, thereby securing safety from high voltage of the fuel cell module during a vehicle maintenance operation and the like.

Abstract: A housing case that houses a fuel cell is provided with mounts for fixing two ends of a lower surface of an end plate that retains stacked unit cells of the fuel cell, and a mount for fixing a central portion of a lower surface of another end plate. Using these three mounts, the fuel cell is fixed to the housing case.

Abstract: A mounting structure of a vehicle body and a fuel cell assembly installed on the vehicle body, wherein a fuel-cell stack is disposed in a front portion of the vehicle body such that the direction of lamination of fuel-cells of the stack is parallel to the lateral direction of the vehicle and such that the power output portion of the stack faces generally in the lateral direction. Terminals of electrodes of the stack partially extend outwardly of the stack, through openings formed through an end plate of the stack, and the terminals are connected through a flexible bus bar to a relay attached to the end plate.

Abstract: A fuel cell apparatus includes a stack of fuel cells, first and second end plates disposed at opposite ends of the stack of fuel cells to press the stack of fuel cells and being connected by a fastening member, and a pressure plate disposed inboard of the first end plate. A concave portion is formed at an inboard surface of the first end plate and a convex portion is formed at an outboard surface of the pressure plate. The convex portion contacts the concave portion. The first and second end plates are coupled to the fastening member (or, a tension plate) by a serration and a bolt. An adjusting portion is formed in the first end plate, and the concave portion is formed in the adjusting portion. A load variance decreasing mechanism is disposed in series with the contact portion of the convex portion and the concave portion. A recess is formed in an electrical insulator disposed inboard of the pressure plate, and the pressure plate is disposed in the recess.
